简要总结
The primary aim of this split-mouth randomized control trial is to compare the rate of canine retraction between the T loop and the Opus loop. The secondary objectives are to compare the angulation of the canine, changes in the first molar position in terms of anchorage loss, and molar rotation for the two loops used T-loop and Opus loop will be placed randomly on the right and left quadrants of patients for canine retraction and outcomes will be measured before and after completion of canine retraction
详细描述
T-loop and Opus loop will be placed in the right and left quadrants of the patient for canine retraction after initial leveling and alignment. canine retraction rate will be measured by using a calibrated caliper every month. canine angulation will be evaluated by periapical x-ray which will be taken before and after completion of canine retraction and anchorage loss and molar rotation will be assessed by model analysis

研究组 & 干预措施
Opus loop
Opus loop will be inserted from 1st molar to canine for canine retraction. it will be activated every month
干预措施: Opus loop (Other)
T-loop
T loop will be inserted from 1st molar to canine for canine retraction. it will be activated every month
干预措施: T loop (Other)
结局指标
主要结局
Rate of canine retraction
时间窗: From enrollment till end of treatment at 4 months
The rate of canine retraction will be calculated by "the amount of canine retraction (in millimeters) divided by the time interval". The amount of canine retraction will be assessed by measuring the distance from the canine cusp tip to the mesio-buccal (MB) cusp tip of the 1st molar with a calibrated caliper at the time of placement of loops and at every month by a single calibrated clinician. The duration will be measured as a time interval and each time interval will be 4 weeks.
次要结局
- Change in canine angulation at start of canine retraction and at the end of canine retraction(From enrollment till end of treatment at 4 months)
- Change in anchorage loss before and after completion of canine retraction(From enrollment till end of treatment at 4 months)
- Change in molar rotation at before and after completion of canine reatraction(From enrollment till end of treatment at 4 months)
